To all whom t may concern.' p

Be it known that I, CLARENCE A.; Horta citizen of the United States, residing in Buffalo, in the county of'Erie and State ofv have invented new and useful New York,

Conveyers for the Butt Improvements in Removers of Corn Huskers,` &c., the following isa specifica-tion.

This invention relates to a conveyer for propelling ears of corn and Vmoreparticularly to a conveyer for use in an apparatus for removing these ears and l In machines of this character, asy hereto- "fore constructed the conveyer which propelled the ears past the gaging and cutting mechanism was provided -with rigid feed or carrying wings which -frictionally resisted Athe movement of the ears toward the gage under the action of the positioning device 'and thus interfered with the positive gaging of the ears.l f The objectpof this invention is Vto provide the conveyer with carrying members which are pivoted on the conveyer and present a rolling surface tothe ears of corn whereby the same are free to be moved cro-sswise of the conveyer and toward the gage under the action of the positioning device and thus ensure proper gaging of the ears at all times preparatory to cuttingoiii the butts thereof. Y,

In the accompanying drawings: I Y Figurel is a top plan view'ofa machine for removing the butt ends of ears -of corn equipped lwith my improvements. Figure 2 is a fragmentary side elevation Of the same, on an enlarged scale. Figurel 3 is a cross section taken on .line'3-3, Fig. 2. Figure il is a fragmentary vertical longitudinal section, on an enlarged scale,- taken on line 4-4,Fig.3.ll l

Similar characters of reference referto like parts throughout' the several views.

10 represents the main frameof the machine ywhich may be of any suitable construction lto support the several working parts of the machine.Y y Y, p A l, l On one side of therear part of the frame is mounted .the cutter whereby the butt ends of the ears of corn. 11 are cut from the bodies thereof for the purpose of severing the stubsor stems therefrom and Aalso loosening the liusks adjacent to the rearmost of which the butt ends of ears of corn preparatory to removing the husks from cutting the kernels therefrom.

kernels ofthe ears. This cutter' may be variously constructed but as`7sliown in the drawings, the same consists of upper and lower ,blades 12,13,I which. have inclined cutting edges arranged 'to converge rearn wardly so that when the buttpendrof an ear is moved against these cutting edges the same will be severedfrom the body `of the ear.

The earsof corn which `areto be trimmed preparatory to being huskedare' placed in a crosswise position on the fro-nt part of a tab-le 14: where thesame vare engaged by a longitudinal conveyerV which moves theV ears past the positioning means and the end orV butt cutter. .InV its preferred form' this conveyer includes a plurality of. longitudinal chain belts 15 arranged side by side and movable forwardlyl with their operative upper stretches." n'

For the purpoeof enabling the conveyer` to positively carry the ears of corn, carrying means are provided which are constructed to form a rolling surface on the conveyer.; These carrying means consist of a plurality of transverse rows of rollers 16 arranged at suitable intervals on the conveyer and projecting laterally therefrom or perpendicu-y larly to the face of the active part of the convey'er. Each of these rollers is pivotally mounted on one of the chain conveyer belts by meansl of a pivot pin 17 which projects laterally from this belt. This pin is provided'at its inner end with a reduced neck 18 whicli'is secured to the chain belt while its outer end is provided with a head 19 so that? the rollerv 16 journaled on this pin is heldagainst axial displacement between the chain belt `and the head 19,- as best showny in Fig. 4:.

These .ears of corn are carried forwardly in a cross-wise position while engaged lon their undersides by the conveyer beltsy and on their rear. sides by the carrying rollersrv and before reaching the cutter the same are moved transversely relatively to the conveyer belts andvcarrying rollers and toward' a gage by .a positioning or placing device so that` the ears are severed properly at the butt ends thereof. In its preferred form the gaging device is constructed as follows:

20, 21 represent the upper and lower lon- O'itudinal bars of a Ua e which are suitabl a z: g y

.mounted on lthe mainframeand form a lonicc . arranged are arranged slightly outsidev of the cutting'` line ofthe cutter, so that when an ear is 'en aged atits butt end with the gage bars ant its stub projecting through the slot bel `lengthwise of its. axis and for this purpose the same is. guided at one end in an .opening 25 in the upper guide -bar 20', while its opposite end is journaled. in, a transversely reciprocating head 26 but compelled tomove with the latter horizontally and transversely of the conveyer. The shifting rod and iin'- gersk are yieldingly held. in a position in which the latter depend froml therodv and into the path of the ears of corn, this being preferably accomplished by a spring 27 surrounding the rod and connected at one end thereto while its opposite end isy connected with the shifting head. As the ears, during their forward movement, 'engage with the .fingers the latter are shifted sidewise and caiiy'the ears withtheir butts against the gage and at the same time the fingers are lifted by the ears until the latter clear the same, after which the fingers are again .returned to their normal pendent position ready to be engaged by the next ear. In order to positively arrest the return swinging motion of the fingers so that they always stanti in` a definite position relatively to the path of the ears a stop device is provided which preferably consists of a fixed stop shoulder 28 a-rranged on the'upper gate-bar and a stop arm 29 arranged on the shifting armI and adapted to slide on said shoulder and also arrest the return movement of the fingers when the latter reach a position perpendicular to the path of the ears of corn asy the same are moved forwardly by the conveyer.

The reciprocating motion of the shifting rod and the parts associated therewith isV produced by means which are so constructed that when this rod or the fingers mounted thereonshould strike an obstruction or meet with unduly strong resistance, this actuating device will yield and thus avoid breaking of parts or clogging of the machine. Thepreferred means for accomplishing thisvpurpose includev an upright rock lever having an upper arm 30 and a lower arm-31,4said' upper arm being pivoted at its lower end by a pink 32 on a bracket forming part or the main frame while its upper end is 'pivotally connected with the shifting head 26, and said lower arm `having its upper end pivoted on said pin 32l and provided with an upward extension 34 which is yieldingly connected with said upper arm. This yielding connection comprises a tension rod having its inner endguided in an opening 36 in the bracket 33 and its outer end pro-A vided with a collar whileits intermediate part vhas a longitudinal slot 38 in which the upper arm moves freely but the central part ofsaid extension is pivotally mounted therein by a pin 39.` The upper arm and the eX- tensionV of the lower larm 'are held yieidingly together by a spring 40 which surrounds the outer part of the tension rod and'bears at its outer end against the lcollar 37' while itsv inner end bears against a sleeve 41 which:v

slides on the tension rod and engages with the outer side of the upper lever. The rock"V lever is turned in a direction in which its upper arm swings outwardly and its lower Y arm inwardly by means of a spring 42`wl`iicli surrounds the inner part of the tension rod and bears at its inner end against said bracket 33 while its outer end bears against a collar 43swhich is secured' to the tension rod. The operative movement of the rock lever in which its upper arm moves inwardly and its lower yarm outwardly iseffected by a rotary cam 44 which engages the lower arm of this. lever.y When the high part o-f'this cam engages the lower lever arm the lever is moved ina direction for causing the shifting rod and fingers to move forward and shift'an ear of corn transversely on the conveyer and toward the gage.`

47 represents a shaft journaled transversely in suitable bearings on the main frame and having sprocket wheels 48'securedthereto around which the chain belts of the longitudinal conveyer pass. The driving shaft 47 is operatively connected with the cam 44 by a driving sprocket wheel 46 mounted on the driving shaft, a driven sprocket wheel 49 connected with. vthe cam 44, and a chain belt 50 passing Varound said driving and driven sprocket wheels. The sprocket wheel 49 and the cam 44 are preferably formed in one piece and journaled on a pin 5'1" secured the ears laterallyT against the gage prepara tory to cutting the butt ends of the ears, thereby insuring easier and better removal of the husk and kernals by the subsequent operation of the husking devices and kernal cutting devices.

I claim as my invention.:
